| Sustainable forest management is more than limiting harvesting volume of timber in tall forest areas. Reclamation and restoration of depleted forest areas is gaining importance as areas of remaining tall forest are diminishing. Irrespective of the causal factors be it unsustainable logging, mining or forest fires, secondary forest resulting from these activities deserve special attention. In East Kalimantan a wide variety of trees has been used for reforestation of areas affected by the devastating fires of 1982- 1983. These attempts involved exotic as well as indigenous species, and results varied considerably. The 1998 fires that raged through the area sadly destroyed most of the successful trials. Gradually emphasis of reforestation has shifted towards... |

| Among collections recently (1979) made in the surroundings of Kutacane, Aceh, N. Sumatra, by Mr. and Mrs. De Wilde, a grass has turned up which proved to be a species of Chikusichloa Koidz., a genus sofar known only from South China, Japan, and the Ryukyu Islands. As this is a very interesting find and since the genus is new for the Flora Malesiana area, a few notes seem appropriate. Chikusichloa was originally described in the Paniceae by Koidzumi (1925), based on C. aquatica Koidz. from Kyushu. The author pointed out a resemblance to Zizania L., which is now considered to belong to the Oryzeae. Honda (1930) recognized its special position and created a subtribe Paniceae-Chikusichloeae. Keng (1931) correctly placed it in the Oryzeae, pointing out possible... |

| Further investigation into the evolutionary relationships of the vireya group of Rhododendron, utilising nuclear DNA sequence data, has demonstrated that this group of species is monophyletic, and a revised classification is presented. The name Vireya is predated at sectional level by several other valid names and the correct name for the section is now Schistanthe. Within Schistanthe, four subsections are recognised: Discovireya, Euvireya, Malayovireya and Pseudovireya. Revised identification keys are provided. Some morphological features of value for classification and/or species delimitation are briefly discussed. |

| ”It is with books as with men: a very small number play a great part, the rest is lost in the multitude.” (Voltaire) On 14 May 1986 the Dean of the Flora Malesiana and founder of this Bulletin, Professor Dr. Cornelis Gijsbert Gerrit Jan van Steenis, died at the age of 84½ years in a hospital in Leiden. He had been there for some abdominal complaints and a slight fever: an abscess on the appendix, perhaps. It was therefore a shock to all of us when he so suddenly and unexpectedly died. A small ceremony was held at the Rijksherbarium on 26 May. In line with his scientific and agnostic attitude he has bequeathed his body to Science. Our sincere condolences are extended to his wife, the famous Mrs. M.J. van Steenis-Kruseman, his son and daughter and all others... |

| In Malesia the genus Sporobolus R. Br. (Gramineae) is represented by 4 sections, 3 here newly distinguished, with 10 species, 2 new. Sporobolus indicus (L.) R. Br. has 5 varieties, 1 new, and 3 with a new rank: var. creber (De Nardi) Veldk., var. flaccidus (R. & S.) Veldk., and var. major Baaijens [S. creber De Nardi, S. diandrus (Retz.) Beauv., and S. fertilis (Steud.) Clayton, respectively]. Some other non-Malesian taxa have also been reduced to varieties, e.g. S. laxus Simon from Queensland (var. queenslandicus Veldk.), and S. pyramidalis Beauv. [var. pyramidalis (Beauv.) Veldk., incl. S. jacquemontii Kunth] from Africa and America. The Indian species generally known as S. tremulus – a superfluous name for S. virginicus (L.) Kunth -is reduced to a... |

| In the Cyclopaedia of Malaysian Collectors and Collections, Mrs. M. J. van Steenis-Kruseman (Flora Malesiana I, I, 1950, 248a, 527b) stated that plants of Herb. Houttuyn, which Houttuyn had acquired from various collectors, were subsequently incorporated in other herbaria, that of Burman in particular. Merrill had questioned this in his work on Houttuyn (J. Arn. Arb. 19, 1938, 291—375, reviewed in Fl. Mal. Bull. no. 17, 1962, 906), as he could not locate a single sheet of Houttuyn’s collection. He only mentioned (l.c.p. 310) that in the Copenhagen Herbarium, in Herb. Vahl, there would be a fragmentary specimen of Myristica fragrans on the back of which was noted ‘ded. Houttuyn’. We could not find this photographed in the IDC microcards of Herb. Vahl. |

| This long-awaited volume is the last of the new Flora of New Zealand and treats 121 genera in 21 tribes with 460 species, of which 226 are introduced and 46 ‘transient’, i.e. introduced but not persisting, against 188 native ones of which not less than 157 are endemics. Most of the latter belong to the Poeae (49 + 41 others), Agrostideae (45 + 58) and Danthonieae (43 + 15) showing the present temperate nature of the grass flora. This structure of the grass flora is briefly discussed, but its origin is considered ‘unsuited to a flora’. It is a pity that no reference is given to a place where this is done, instead. Of general interest to the New Zealand Flora is the extensive literature list (‘annals’) completing the ones given in previous volumes with... |

| In 1759 Linnaeus described an American species under Gentiana, as G. verticillata. In 1781 his son recorded (Suppl. 174) a specimen from India leg. D. D. Fabricius under the same name, without reference to the earlier G. verticillata, and gave a full description. Whether this was just a new record or whether he really intended to describe a new species, which then involves that he was not aware of the name his father had preoccupied, is difficult to prove. No references were mentioned though he gave these elsewhere under other species described before. Though Index Kewensis did not enter this homonym I am rather convinced that it was intended as a new species, also in connection with the fact that he based the description on an Indian specimen.... |

| DUNCAN, B.D. & G. ISAAC. Ferns and allied plants of Victoria, Tasmania and South Australia. Melbourne University Press, Melbourne. 1986. xii, 258 pp., line drawings, maps, b/w photogr., 8 col. pl. In Europe available from HB Sales, Littleton Road, Ashford TW15 1UQ, U.K. Ł 25.00. ISBN 0-522-84262-3. A beautifully and lavishly illustrated, thorough account of the 128 ferns and fern-allies of the Southernmost extremities of the Australian subcontinent. For the Malesian oriented scientist primarily interesting because of the excellent view it offers of a flora that is close to the Malesian flora on the generic level (almost 90% of the genera enumerated in common) and at the same time very distinct on the specific level (hardly 16% in common). |

| The thin formidable-sized folio book by J.G.S. van Breda ‘Genera et species Orchidearum, etc.’ is a little-known publication even to orchidologists, as most of the new names proposed in it have disappeared into synonymy long ago. It was never finished, only three fascicles of the eighteen promised are generally supposed to have been published. For their publication dates see De Wit (1950) and Stafleu & Cowan (1976). In the library of the former ‘Koloniaal Museum’, Haarlem, the Netherlands, now the ‘Koninklijk Instituut voor de Tropen’ (KIT), Amsterdam, the former draughtsman of the Flora Malesiana Foundation and amateur orchidologist J. Vuijk found a copy which contained not three, but four fascicles. At that time this was merely briefly noted (Van... |
